Brief summary

Upper respiratory infections (URIs) have long posed a significant burden to the US healthcare system. Well before the coronavirus disease of 2019 (COVID-19) pandemic they have been among the most common acute outpatient illnesses, causing 75-100 million physician visits each year on average, and costing the health care system billions of dollars annually. This double-blind randomized placebo-controlled study tested the efficacy of two anti-inflammatory throat sprays against placebo and against a throat spray taken in conjunction with 325mg of aspirin, a well-known systemically administered cyclooxygenase (COX) inhibitor. Participants having common cold symptoms lasting less than two days were enrolled and given treatment to administer at home. Various common cold symptoms were assessed and measured via clinically validated self-assessment scales. Participants were screened for influenza and COVID-19 before enrollment and were excluded if found positive.

Interventions

DRUGWintergreen Throat Spray and Aspirin Tablet

The liquid spray contained wintergreen oil, menthol, lactoferrin, lysozyme, aloe, and glycerin. Aspirin in a 325mg tablet

DRUGAspirin Throat Spray and Placebo Tablet

The liquid spray contained 6mg dissolved acetyl salicylic acid per dose, menthol, lactoferrin, lysozyme, aloe, and glycerin. Placebo Tablet: Looked like the treatment aspirin tablet but contained no drug and only inactive excipients.

DIETARY_SUPPLEMENTWintergreen Throat Spray and Placebo Tablet

The liquid spray contained wintergreen oil, menthol, lactoferrin, lysozyme, aloe, and glycerin. The placebo tablet looked like the treatment aspirin tablet but contained no drug and only inactive excipients.

OTHERPlacebo Throat Spray and Placebo Tablet

The placebo spray contained vehicle buffer, a sub-therapeutic dose of menthol, and a sweetener. The placebo tablet looked like the treatment aspirin tablet but contained no drug and only inactive excipients.

Design outcomes

Primary

MeasureTime frameDescription
Relief of Sore Throat Pain36 hoursA time-weighted summed difference in pain intensity on the sore throat pain intensity scale (STPIS) after the first dose of medication (STPIS 1st entry Day 1 compared to STPIS 4th entry Day 2). On the STPIS, 0mm, the leftmost point of the line, represents no throat pain, and 100mm, the rightmost point of the line, represents the most severe throat pain.

Secondary

MeasureTime frameDescription
Clinical Efficacy Against Common Cold Symptoms48 hoursSecondary endpoints will include changes to the Modified Jackson Score, measured from Absent=0, Mild=1, Moderate=2 to Severe=3, with a higher score representing worsening of various cold symptoms and a lower score signifying improvement of various cold symptoms.
